In a series of experiments with the chemical carcinogen DMBA (7, 12-dimethyl[a]anthracene), we recently found that exposure of female Sprague-Dawley rats in 50 Hz magnetic fields (MF) in the microtesla range significantly facilitates the development and growth of mammary tumors. One possible explana
